This work focuses on the analysis of the debris found in the lubrication oil produced by the wear
abrasion during wear tests conducted on crowned splined couplings. During each test the presence and the
dimensions of the debris in the oil have been monitored. Tests have been performed by means of a dedicated
splined couplings test rig and they have been performed by imposing an angular misalignment on the axes of
the components.
Results shows that when these components work in misaligned conditions, the relative motion between
engaging teeth brings to the rise of a wear phenomenon called fretting wear.
